Answer: wouldn’t it be 66
Answer:
A. $ 58.50
B. $ 80
C. No, it did not mark up 30%.
Step-by-step explanation:
Since,
![\text{Mark up percentage}=\frac{\text{Store price-Actual price}}{\text{Actual price}}\times 100](https://tex.z-dn.net/?f=%5Ctext%7BMark%20up%20percentage%7D%3D%5Cfrac%7B%5Ctext%7BStore%20price-Actual%20price%7D%7D%7B%5Ctext%7BActual%20price%7D%7D%5Ctimes%20100)
A. We have,
Mark up percentage = 30%
Actual price = $ 45,
![\implies 30=\frac{SP - 45}{45}\times 100](https://tex.z-dn.net/?f=%5Cimplies%2030%3D%5Cfrac%7BSP%20-%2045%7D%7B45%7D%5Ctimes%20100)
![30\times 45 = 100SP - 4500](https://tex.z-dn.net/?f=30%5Ctimes%2045%20%3D%20100SP%20-%204500)
![1350=100SP - 4500](https://tex.z-dn.net/?f=1350%3D100SP%20-%204500)
![5850 = 100SP](https://tex.z-dn.net/?f=5850%20%3D%20100SP)
![\implies SP = \$ 58.50](https://tex.z-dn.net/?f=%5Cimplies%20SP%20%3D%20%5C%24%2058.50)
B. We have,
SP = $ 104,
![\implies 30=\frac{104-AP}{AP}\times 100](https://tex.z-dn.net/?f=%5Cimplies%2030%3D%5Cfrac%7B104-AP%7D%7BAP%7D%5Ctimes%20100)
![30AP = 10400 - 100AP](https://tex.z-dn.net/?f=30AP%20%3D%2010400%20-%20100AP)
![130AP=10400](https://tex.z-dn.net/?f=130AP%3D10400)
![AP=\$ 80](https://tex.z-dn.net/?f=AP%3D%5C%24%2080)
C. We have,
AP = $ 75,
SP = $100,
Thus, mark up percentage = ![\frac{100-75}{75}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B100-75%7D%7B75%7D%5Ctimes%20100)
![=\frac{25}{75}\times 100](https://tex.z-dn.net/?f=%3D%5Cfrac%7B25%7D%7B75%7D%5Ctimes%20100)
![=\frac{1}{3}\times 100](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes%20100)
= 33.33 %
Hence, store did not mark up the price by 30%.
10km+10km*2 = 30km
30km*(1000m/1km) = 30000m
In the second equation of the problem, the kilometers from the initial total distance biked is cancelled out by the conversion of kilometers to meters, as seen in the 1000m/1km (or 1000 meters for every 1 kilometer).
Answer:
8
Step-by-step explanation:
( 12 + 3m ) / 2 = 18
12 + 3m = 18 x 2
12 + 3m = 36
3m = 36 - 12
3m = 24
m = 24 / 3
m = 8
